2 Design philosophy

3 2-way Systems

4 Paper cone to metal diaphragm transition in middle of vocal range Paper cone to metal diaphragm transition in middle of vocal range Low HF crossover point Low HF crossover point High distortion High distortion Low intelligibility Low intelligibility Disadvantages

5 Vented enclosures Sounds OK close to the box but:- Sounds OK close to the box but:- insufficient throw insufficient throw no good outdoors no good outdoors poor directivity control poor directivity control HF keeps going beyond LF HF keeps going beyond LF

6 1981: 3-way System

7 Paper cones throughout vocal range Paper cones throughout vocal range Higher HF crossover frequency Higher HF crossover frequency Less stress on HF driver Less stress on HF driver Lower distortion Lower distortion Better intelligibility Better intelligibility Advantages

8 One box full range vs. bins and horns Modular enclosures Arrayable, stackable Horn loaded High power: 1kW TMS-3 Modular One-box System

9 Horn loading gives higher efficiency Horn loading gives higher efficiency TurboMid device minimises phase cancellation TurboMid device minimises phase cancellation Better intelligibility Better intelligibility Horn loading

10 TurboMid Device

11 1990: 4-way system

12 Extends use of paper cone transducers up to 8kHz Extends use of paper cone transducers up to 8kHz Very high efficiency: 111dB, 1W at 1m Very high efficiency: 111dB, 1W at 1m HF driver under very little stress HF driver under very little stress Point and shoot aiming Point and shoot aiming Hi-Fi sound to all seats Hi-Fi sound to all seats Negligible distortion Negligible distortion Advantages

13 Virtual point source Elegant, safe flying Ideal truck pack Integrated system Smallest, lightest Flashlight System

14 What was wrong with Flashlight? Poor horizontal consistency Poor horizontal consistency Dated rigging and trucking system Dated rigging and trucking system Too many enclosures required for coverage Too many enclosures required for coverage Too big and heavy Too big and heavy

15 Why Virtual Point Source? 2D system design 2D system design Horizontal changes with Frequency and length Horizontal changes with Frequency and length Motor and point intensive Motor and point intensive Poor ground stacking Poor ground stacking Not Scalable – several types of line array size needed with point source fills Not Scalable – several types of line array size needed with point source fills Power hungry Power hungry Output Doubles with distance Output Doubles with distance Line array VPSVPS 3D system design 3D system design Dispersion tailored to suit venue Dispersion tailored to suit venue Good stacked or flown Good stacked or flown Scalable – 1 box does all Scalable – 1 box does all Extra efficiency through horn loading allows minimal power requirements Extra efficiency through horn loading allows minimal power requirements Listener only hears 1 hi mid and hi cabinet at a time Listener only hears 1 hi mid and hi cabinet at a time 3D system design 3D system design Dispersion tailored to suit venue Dispersion tailored to suit venue Good stacked or flown Good stacked or flown Scalable – 1 box does all Scalable – 1 box does all Extra efficiency through horn loading allows minimal power requirements Extra efficiency through horn loading allows minimal power requirements Listener only hears 1 hi mid and hi cabinet at a time Listener only hears 1 hi mid and hi cabinet at a time

16 Why not a line array? Over crowded market place Over crowded market place Fixed dispersion reduces flexibility Fixed dispersion reduces flexibility A single box is not capable of doing 200 people or 50,000 A single box is not capable of doing 200 people or 50,000 Line array effect is rarely relevant accept in a large array Line array effect is rarely relevant accept in a large array Potential Site line issues with large arrays Potential Site line issues with large arrays System advantages are little to do with acoustics System advantages are little to do with acoustics

17 Some typical issues with using Line arrays Opening angles on lower enclosures has no effect on the dispersion of the system Opening angles on lower enclosures has no effect on the dispersion of the system Despite theory, practical designs do not double with distance Despite theory, practical designs do not double with distance Attenuating the middle of the array has little or no effect on directionality of system Attenuating the middle of the array has little or no effect on directionality of system

18 Opening angles has no effect!

19 Line Array at distance

20 Audio hits the balcony

21 Does this mean line array is terrible? Line array is like any tool in an engineers toolbox Line array is like any tool in an engineers toolbox Use it when its dispersion and packaging is correct Use it when its dispersion and packaging is correct Use them for what they were designed for, 1 per side will not work! Use them for what they were designed for, 1 per side will not work! When these dont fit the venue use a point source box When these dont fit the venue use a point source box
